'1 all ac/10m it may concern:

Beitknown that l, iiLnnn'r liROADMEYLR,

a citizen of the Uni edfitates, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new [and j usei'ul l' nprovements in Paper-Feeding i-iuparatus, or which the tollowing is a s' ierification. v

Th present invention relates more particu'larly to means for loosening and elevating the upper sheets of the pile, and the object is to provide simple means, whereby the air blasts ei'n loyed for this purpose can be regulated to the conditions and the character of the Work; 1 p

In the accompanying drawings 1 Figur 1 is aside elevation of a Wellknown type of feeding machine showing the improvements in place thereon, v

Figure 2 is a' reare'levation 01* the same,

Figure 3 is atop plan view,

Figure 1 is a view inelevation on an enlarged scale of the controlling valve,

Figure 5 is a sectional view therethrough on the line 55 of Figure 4, 1

Figure 6 is a. sectional view on the line 6-6 of Figure 5.

In the embodiment disclosed, a suitable frame 7 is employed, in which is mounted the pile of sheets to be ted. Th initial feeding means is in the form of a rotatable suction drum or head 9, and the uppermost sheet of the pile placed on the table 8, is

brought into contact with the drum 9 by an air blast delivered through twinnozzles 10 adjustably mounted on a supporting rod 11 on the rear side of the frame. To eliminate cohesion other nozzles 12 and 13 are adjustably mounted on above opposite sides of the table.

Mounted on the rear portiono'f the trame is a valve casing 14 having depenoing intake nipple 15, an upstanding outlet nipple 16 and two oppositely disposed side outlet nipples 17 and 18. A suitable fan, indicated at 19 and preferably having its intake 20 suitably coupled to the feeding head 9, has an outlet 21 connected by a supply conduit 22 to the intake nipple 15 0f the valve casing 14. The upstanding outlet nipple 16 has a branch pipe 28 connected to the nozzles 10.

a. vertically movable table 8 adapted to carry 1 adapted to be loosened, and the topmost sheet l he nipple 17 is connected by a branch pipe 2e to the nozzle 12, While the nipple '18 is connected by a branch conduit 25 with the nozzle 13.

The central portion of the valve casing 14 has a cylindrical valve chamber 26 that containsa rotary valve head 27 provided With a stem 28 that projects through the outer end of the valve casing and carries a handle This handle is provided with an index pointer 30 cooperating with indicating marks 31 on the front face of the valve casing. A coiled spring 32,tsurrounding the stem 28, bears against the head 27 and the inner end of the valve chamber to hold nient. The head 27is provided with a channel or passageway 33, provioing a pair of oppos te stop Walls 34. The ends ofthe passageway 33 are flared, and each is of sufficient extent to simultaneously uncover two of the adjacent ports in the nipples 15-18. The stops 3 1 are each of sufiicient extent to cover one of these ports and being oppositely disposed Will obviously simultaneously cover two opposite ports.

Assuming the fan in operation, if the valve is moved to open position, its relation Will be as shown in Figure 6, so that air delivered through the nipple 15 into the casing can flow freely through all three ports 16,17 and 18, and thus deliver blasts through the various nozzles 10, and. 13. Under some conditions, it is desirable to cut down the air delivered through the side, nozzles 12 and 13 or cut it otl" entirely. This obviously can be easily accomplished by turning the valve until thestops 34 are more or less across the ports, through the nipples 17 and, 18. The supply of air to all three of the nozzles can also be cut down by moving one of the port: across the intake nipple 15, and this supply ca be completely out off if desired byclosing said intake nipple.

From the foregoing, the constructon, operation and many advantages of the herein described invention will be apparent to those skilled in the art, Without further description, and it Will be understood that various changes in the size,

it thought that construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In paper feeding apparatus, the combination with a paper support, of nozzles for deliverin loosening air blasts to different portions of the sheets placed on the support, and means for relatively varying the amount of air delivered through the v3. In paper feeding apparatus, the com,

bination with a paper support, of nozzles for delivering loosening air blasts to different portions of the sheets placed on the support, a valve casing having an inlet and a plurality of outlets, a supply conduit leading to the inlet of the valve casing,

a plurality of branch conduits leading from the casing to the difierent nozzles, and a valve in the casing for controlling the supply to the branch conduits to vary the amounts of air delivered therethrough.

4:. In paper feeding apparatus, the combination with a rear nozzle and side nozzles for delivering blasts of air to different portions of the sheets placed on the support, a valve casing having an inlet and a plurality of outlet ports, a supply conduit connected to the inlet port, a plurality of branch pipes leading from the outlet ports to the nozzles, and a rotary valve in the casing having stops that are movable across the ports to vary the amount of air passing therethrough.

5. In paper feeding apparatus, the combination with a rear nozzle and side nozzles for delivering blasts. of air to different portions of the sheets placed on the support, a valve casing having an inlet and a plural ity of outlet ports, a supply conduit connected to the inlet port, a plurality of branch pipes leading from the outlet ports to the nozzles, a rotary valve having a passageway therethrough, and spaced stops movable simultaneously across certain of the ports, and means for indicating the location of the stops.

6. In paper feeding apparatus, the combination with a paper support, of a plurality'of nozzles for delivering loosening air blasts to different portions of the sheets placed on the support, means for supplying air to the respective nozzles, and means in the air supply means for relatively varying the amount of air supplied to said nozzles.

In testimony whereof, I afiix my signature in the presence of two witnesses.
